What's the difference between "Anatella Installer" and "Anatella portable"?

These 2 versions of Anatella are identical.
The "Anatella Installer" software performs some additionnal work during install:

it associates .anatella files with the Anatella software

it optionnaly creates a new entry in your "start menu"

it makes sure that you have write access inside the "plugin" directory of anatella (otherwise you cannot add new user-defined Anatella plugins)

Additional optional downloads

To extend Anatella with new functionnalities, you can program new "boxes" in many languages. Anatella supports the following languages:

R: To use the R language inside Anatella, you need to install an additionnal component: The "R engine". R is quite slow and cumbersome to use but possesses a large library of functions. Also, the charts in R are beautiful.

Python: To use the Python language inside Anatella, you need to install an additionnal component: the "Python engine": 64-bit Python Engine or 32-bit Python Engine. Many people chose chose to use Python because of its easy syntax: i.e. You can create very quickly&easily new "boxes" using Python. The drawbacks of Python are the same as the drawbacks of R: quite slow and limited to small datasets (because of the "in-RAM" memory limitation).

Javascript: Javascript is the most common scripting language. It's also very fast. Inside Anatella, Javascript allows you to create new "boxes" that runs in "streaming mode": Because of the "streaming mode", you can process unlimited datasets sizes when coding in Javascript. No additional component is required to code in Javascript. Anatella extends the R & Python engines so that they also support a "streaming mode" (to process unlimited dataset sizes), although it's not as fast and flexible as the Javascript streaming mode.

C/C++: You can use the Anatella C/C++ SDK for the ultimate performances and flexibility. Ask a sales representative to get the SDK.

Anatella uses the standard ODBC&OleDB technique to access databases.
